TPA3140D2: Asking fort the possible solution to support 16ohm 12V to 5Watt

Part Number: TPA3140D2


Hi team,
Customer uses the TPA3144 and cannot meet 5Watt output at 12V/16ohm.
Can TPA3140 aceieve this output power? or it is the PVDD constrain?
If increasing the PVDD, can the issues be fixed?

This is the TPA3144 THD @ 12V/16ohm case.
